qgis3: Monterey 12.7.5 Build Error with Fix

[multiquadric]

Memorializing an issue rather than seeking a fix. Apparently the use of "use_xcode" with Qt5 is (was) problematic across MacPorts, Qt5 being the challenge.

The OS was not a fresh install. 2013 Mac Pro (trash can).

The install log error led to this file: /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py-pyqt5/py312-pyqt5/work/PyQt5-5.15.10

Here, in the Portfile, this change was made: "use_xcode yes" to "use_xcode no"

The build and install completed.

To what are you referring?

Could you share what error was in the log?

Here, in the Portfile, this change was made: "use_xcode yes" to "use_xcode no"

The build and install completed.

use_xcode yes was added to fix #65410.

The results of general sleuthing for answers. ​https://github.com/macports/macports-ports/commit/fd73bce64330dac7e02aba0f3f37582999b49330#commitcomment-77072145 ​https://github.com/macports/macports-ports/pull/15535 Etc., etc.

macOS changes vs. QT5 requirements?

The proposed change would be harmful for most users.

The problem is likely caused by a not-quite-right install/config of Xcode, for which a quick and easy fix is reported on Stack Overflow: ​https://stackoverflow.com/a/41524934/2288076

Mostly agree, per above. The cure? Not sure.

For fun (!), I can try a build after messing with "xcode-select". If the build completes, terrific.

No changes were needed on a newer box with Apple Silicon and macOS Ventura.

The "bug report" was not so much for a fix. macOS Monterey is an older OS. And Qt5 looked to have caused some headaches. I thought the "xcrun --show-sdk-path" command returned the proper path.

Update! Good news.

Mac Pro (Late 2013) macOS Monterey 12.7.6 (21H1320) Clean install (disk erase, OS install, MacPorts install, QGIS3 and QGIS3-LTR installs) Both QGIS3 and QGIS3-LTR builds completed successfully.

Assuming the py312-pyqt5 problem was related to a series of Xcode and command-line tools updates on the same Mac Pro vs. the build logic for py312-pyqt5. Everything else had compiled without error.
